Liatris punctata


Dotted blazing star, Dotted gayfeather


Asteraceae (Aster Family)



Liatris punctata (Dotted blazing star)
Wasowski, Sally and Andy
The erect, unbranched stems of this perennial may be solitary but are usually in clusters, 1-2 ft. tall.Several stems bear narrow, crowded heads with rose-lavender flowers arranged in slender wands. Numerous narrow leaves are crowded along the stem as they intermingle with the tufted flowers. Disk flowers crowd together to form a lavender spike encompassing the top third or half of the stem.

Rayless heads of purple flowers and slender, often plume-like bristles on the fruits generally identify this complex genus of the East that barely extends into the West.

The species name punctata means dotted and refers to the speckled leaves.
